Grid Lines in Graphs are Rarely Useful - Perceptual Edge

Graphs are constructed using axes—lines that serve as boundaries for the space in which the data is displayed, along which scales appear to assign meaning to the data. Two major types of scales appear in graphs: quantitative and categorical. Quantitative scales assign numeric values to equidistant locations along an axis.

Comparison of UCS to Bond Work Indices

UCS. The Y-axis on this graph measures Wi C+Wi RM+Wi BM. The sum of the Bond Work Indices fails to show a relationship to UCS. A related graph plotted UCS versus the total comminution energy required to grind a 100 mm rock to 200 microns. The distribution of points was similar to Figure 7; thus, total energy failed to show any relationship to UCS.

Energy Use of Fine Grinding in Mineral Processing ...

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall …

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify …
